FURNACE RETORT Filed June 20 1921 J. W. M LAUGHLIN ET AL 3 Sheets-Sheet 2 is secured at each end a head as head 9 or 10.

tically gas or air tight whereby gases and vapors are prevented from passing outwardly through this trunnion. As a part in this construction a gas tight joint is provided at 16 between the end of the rotatable trunnion l1, and'a relatively fixed member of the feeding-in mechanism '15.

Means as 17 with clutch as at 18, is provided for efi'ecting; the rotation when desired of the retort shell as a whole, and it; will be herewith remarked that the rctortilshell is continuously rotated when the retort is functioning. The trunnion 11 is "frequently referre' to as the trunnion at the feed or intake end of the retort. The hollow trunnion 12 at the other end is referred to as the trunnion at the discharge end of the retort and the outermost end of trunnion 12 enters a hollow stationary member 19, con-- stituting a part of the discharge mecln'inisn'i 20, whereby the partially distilled coal residues can be passed from the retort to the places desired. The construction of the discharge mechanism is such that the residues from the retort can be passed to the places desired without permitting the escape of gases or vapors from the interior of the retort through the discharge mechanism or Without permitting the entrance of air into the retort.

he retort, or in other words, casing member 19 thereof, is provided with suitable gas oll'talre means as piping; 21, whereby the gas and vapors evolved during partial carhoniza'tion or distillation process can pass from the retort for the desired disposition as to the gas cleaning); and scrul hing; apparatus and to the holder.

An air or gas tight joint is provided as at 22 between the hollow trunnion 12 on the one hand and the stationary casing 19 on the other. The trunnions at each end of the body member of the retort shell are -centi-ally located, or in other words. th

common axis of the two trnnnions constitute the axis about which the bod; member of the retort shell rotates. ll ithin the re tort shell or body member thereof there is located a longitudinally extending bar or rod, preferably in the form of a railroad rail, and this bar or rail constitutes a mem her which ell'eots' or assists in cilmtting the agitating. of the material while the retort within the retort.

The bar or rail 23 also serves to prevent the formation of any incrustations on the interior of the retort shell or at least serve to effect a removal of incrnstations which may become deposited upon the interior of the retort shell, should there be such. The bar or ail is freely movable, in other words, it, is free to rise and fall as the retort shell is rotating, this automatically accomplishes the ends desired. The specific form of the bar, to wit, in the form of a railroad rail, which. has a head, weh and bottom flanges is particularly useful in that the flange portions serve not only to crush but to actually out by the falling of the rail. A rail thcretore has the cutting effect similar to that of a dull chisel, or a series of chisels, and lecause of this characteristic, is ticularly advantageous this place.

A chain,'as is located Within and practically extends through the hollow trunnion 12 at "the discharge end of the retort. This chain is secured at one end as 25, merely to retain the chain in place but otherwise the chain is free to move within the hollow trunnion 12. The chain may therefore be properly described. as a freely movable interior of the retort through the trunnion on its way to the discharge mechanism.

The residue delivered fromthe retort is relatively small, the larger particles being about the sizeof a pee.

The shell of the retort ma be of any suitable material which will withstand the work that it must perform and which will also mittcd to and through the walls of the retort to the material being treated within the retort shell, the retort being gas tight, except for offtake means by which evolved vapors and gases parts from the retort; the

retort being provided with jmeans for feed chain and it functions to assist in the clearing of the material as it passes from the pad means For feeding the coal into the shell while being rotated, the conslruction also living smell that the solid residues can pass from the retort shell while being rotated and surh that vapors and gases can be withdrawn for collection while the retort shell i being rotated, the furnace-retort being characterized b'v havin a freelywmovable bar located within the hody memer of the shell of the retort and'also by having a freely movable chain. extending through the hollow trunnion at the discharge end.

A furnace-retorthaving a rotatable retort shell, mounted in respect to the masonry structure of? the furnace in such a manner ighat heat from the furnace can transmitted Lo and through the Walls of the re;

tort to the material being treated within the retort shell, the retort being gas tight, except for oiltake means by which evolved vapors and gases pass from the retort; the retort being provided with means for feed. ing coal or analogous material thereinto at one end and with means wherebythe solid residues can pass from the interior of the retort at the other end, said retort havinglocated in said rotatable shell a mem her which is free to rise and fall as the retort rotates.
